Was using bit defender 2010 on my main pc licence ran out and have been running this ever since, no problems to report, successfully found any virus's lurking and seems to run quietly in the background too. Windows 7 64bit.
For friends PC's whereas I used to install AVG or Avast, have been putting this on, a lot easier and unlike AVG it doesn't ask you to uninstall and reinstall the latest version every year.
There are three main downloads for this,
XP 32 bit
vista/windows 7 32bit
vista/windows 7 64bit.
Thumbs up from me.
